The 26-year-old has been in and out of jail five times. She has been on probation since 2007 when she was first caught drunken-driving, reported Sun online.

On consuming cocaine, she said, "Everyone thinks I've done it so many times. But I've only done it may be four or five times in my life. And I got caught twice.

"It's the truth. I've never taken heroin either, never injected myself with anything, never done LSD. Those things all scare me. Pot I've taken, obviously for ecstasy. I liked that better than the others."

Lohan recently checked into the Betty Ford Clinic for her 90-day treatment order as part of a plea deal she struck in a court in a car accident case.
